I am showing the several figures or views by way of ex ample forillustrative purposes and for a better and clearer understanding of myinvention, and not for limitation purposes.

The size of the parts shown in the drawings herein, and the spacingtherebetween, being exaggerated for clarification purposes.

The outer cutter member, indicated by arrow 4, comprises a lower section7 having side wall sections 8 and a floor portion 8' provide-d with anopen space 8"; and also with an upper section 9 having a shear-face 11and side wall portions 12 which are secured to the wall sections 8 bysuitable means, for example, electric spot welding or the kind, unitingsame into a unitary structure.

Arrow 5 indicates the inner cutter member for being positioned withinthe outer cutter member to cooperate therewith for shaving purposes. Theinner cutter member comprises an upper section 15 having a shear-face 16and side wall sections 17; and also having a lower section 18 providedwith wall portions 19 and with a floor section 21. The wall portions 19are secured to the wall sections 17 in a manner as are the walls 8 and12 above mentioned. The floor section 21 is provided with two spacedapart channeled sections 22 and with recessed, grooved, or slottedportions 24, and with an opening 25 for housing therein a portion of anactuating element 26 for operable shaving purposes (FIG. 7).

The base member or element (indicated by arrow 6) comprises a channeledstructure having spaced wall sections 31 each provided with recessedportions or openings 32, and with a floor portion 33 having an opening34 provided with side portions 35 each having a flange section 36. Theend portions 37 and 37', of the floor portion 33, are each provided withsuitably-shaped flange sections or extensions 38 and 38, each of theseextensions 38 and 38 are provided with a bead or depressed portion 2(FIG. 9) for a purpose which will be hereinafter explained.

Arrow 41 indicates a coil-spring in an expanded position, of suitablelongitudinal shape cross-sectionally, provided with a lower coil or ring42 and with an upper coil or ring 42'.

My cushioning shearing section may be assembled in the following manner:

The coil-spring (arrow 41) is positioned upon the floor 33 of the baseelement (arrow 6), the lower coil or ring 42 is moved in a slidablemanner upon the side portions 35 (FIG. 4) underneath the flange portions36 until the front portion 43, of the coil-ring 42, becomes located uponthe portion 37 of the floor 33 and the rear portion 43' becomes locatedupon the portion 37, and the side portions 44 of the ring 42 are eachlocated upon one of the side portions 35 of the floor 33. The flangeportions 36 are yieldable to a desired degree so as to-permit theslidable movement of the coil or ring 42 and then hold the spring 41 ina desired upright position.

My cushioning shearing section may be assembled in the following manner:

The cutter member indicated by arrow 5 may be posi tioned within thecutter member indicated by arrow 4, having its shear-face 16 underylingthe shear-face 11, thus forming an operable shaving unit (as indicatedby arrow 19 FIG. Such unit is then placed in a downward manner into thebase element indicated by arrow 6 FIG. 3, in a manner whereby the upperportion of the coil-spring 41 may pass through the opening 8" of thefloor of the outer cutter member arrow 4, for having its upper coil ringengaging the inner cutter member arrow 5, wherein the upper coil or ring42 may nest itself within the channeled sections 22 and within therecessed portions 24.

The side wall portions 31, of the base element arrow 6, are flexible toa degree whereby such wall portions 31 may be spread outwardly to anextent permitting the insertion of the outer cutter member 4therebewteen; during such insertion the outer cutter member 4 is urgeddownwardly until each of the outwardly disposed portions 14 snap intoopenings 32 (FIG. 8) of the wall portions 31; such portions 14 areadapted to move within such openings 32 in a manner whereby the shavingunit may move transversely relative to the floor portion 33, of suchbase element 6, (see FIG. 10). These portions 14 are adapted duringupward movement to engage the upper end portion 14', of the openingarrow 32, (FIG. 8) holding the shaving unit in position upon the baseelement 6, preventing accidental removal therefrom and also to preventlongitudinal movements of such shaving unit relative to its baseelement.

From the above it is clear, that when my shearing section is fullyassembled, the coil-spring 41 will be held firmly in position upon thebase element 6, having its upper coil or ring 42' engaging portions ofthe floor 21 of the inner cutter member 5, urging same upwardly forhaving its shear-face 16 into frictional engagement with the shear-face11 of the outer cutter member 4 for shaving purposes, and simultaneouslytherewith such coilspring 41 will provide resilient means for urgingsuch shaving unit into transverse movements during shaving operation,enabling such spring 41 to become automatically expandable and alsocompressible to enable the shear-face of the shaving unit to tilt ormove to adjust itself during shaving operation transversely relative thebase section 6 (see FIG. 10).

The movements of the inner cutter member 5 during shaving operation willcause the coil-spring 41 to vibrate and thus shake sheared hair off itscoils.

While shaving the coil-spring 41, which is in normal expanded position,may become automatically compressed and/or expanded to desired degreesfor supporting the shaving unit in its tiltable or retractable movementsthereby facilitating such shaving operation.

Thus, my invention as disclosed herein, comprises a fullycompletely-assembled individual shearing section for a shavingimplement. Such shearing section may comprise (as may be required) asingle shaving unit or a plurality of individually assembled shavingunits, and be made in various shapes, styles, or forms; the disclosuresherein are for illustrative purposes only and not for limitationpurposes.

My present assembled shearing section comprises, as above pointed out, ashaving unit consisting of an outer cutter member 4 having an innercooperative cutter member 5, and a base element 6 housing the shavingunit, and a coil-spring structure 41 carried by the floor portion 33 ofthe base element 6 for engaging the inner cutter member of the shavingunit to cause frictional engagement between the shear-faces thereof, andsimultaneously therewith such spring structure is providing tensioningmeans for supporting such shaving unit during its transverse tiltable orretractable movements while shaving.

The fact that the coil-spring 41 is positioned loosely Within theopening 8" in the floor 8 of the outer cutter member 4, and is able toutilize freely the full space between the floor 33 of the base element 6and the underface 21 of the inner cutter member 5, will greatly reduceresilient strain of such coil-spring 41 and case its movements thusfacilitating its operational action.

Such as assembled shaving unit is a practical and useful structure. Itcan be utilized as a unitary shaving unit, secured to the handle and/ orremoved therefrom as such unitary shaving unit, and is marketable as anassembled shaving unit.

In FIG. 7, I am showing a longitudinal cross-sectional view of one of myshaving unit (secured to my carrier arrow C), disclosing the coil-spring41 being in normal expanded position, urging the shear-faces 11 and 16into frictional engagement with each other, and simultaneously therewithsupporting the shaving unit in its upward position for shaving purpose.And in FIG. 10 I am showing a cross-sectional view of two of my shavingunits carried by one carrier, wherein one of such shaving units being ina position similar to that shown in FIG. 7 (see arrow U), and the otherof my shaving units being in a retracted position (see dotted lines19"), movable transversely relative to the floor portion of the carrieror that of the handle seat. It is thus clear that one or more of myshaving units may be utilized simultaneously for shaving purposes, beingremovable and/or replaceable as individually-assembled shaving units.

My carrier comprises a suitably shaped structure for example asindicated by arrow C (FIG. 6), wherein the floor portion of such carrieris provided with an open section 51' having side portions 51 and sideflange sections 52 and 52' and wall portions 53; the flange sections 52and 52' are each provided with depressed or bead portions 3, for apurpose which will be hereinafter explained.

The base element indicated by the arrow 6 (FIG. 3) may be secured to thecarrier arrow C in any suitable manner for example, the flange portion52 may be positioned between the flange portion 38 and the floorportions 39 (see FIG. 9), and the flange portion 52' may be positionedbetween the flange portion 38' and the floor portions 39' (see FIG. 3),and then by moving the shearing section slidably into position upon thecarrier the snap fastener 2 of the flange 38, or 38 (FIG. 9), willbecome interlocked with the snap fastener 3 of the flange portions 52and 52' (FIG. 6), thus holding the shearing section in desired positionupon the carrier C.

The walls 53 of the carrier C are each provided with a curved endportion 54 (FIG. 7) terminating into an inclined section 63 adapted tofit or snap into the recessed portion 64 of the handle-casing 56, thusholding the shearing section upon such handle-casing for shavingpurposes.

The handlecasing 56 is provided with a recessed section 61 forming aseat for the assembled shearing structure, this recessed section 61 isprovided with a non-punctured floor having wall portions 62, and alsohaving an upwardly extending section or boss structure 67 (FIGS. 7 and11); this boss structure 67 is provided with a through opening 66 forhousing therein an actuating element 26 to engage and operate the innermovable cutter member for shaving purposes. The element 26 is providedwith a recessed shouldered portion 69 (FIG. 11) to support therein aresilient cover or collar 68 adapted to cover the boss opening 66, andsimultaneously therewith to shift sheared hair away therefrom thuspreventing the access of sheared matter into the motor compartment (notshown).

The above has been explained by way of example only and not forlimitation purposes. Various other suitable means may be utilized tobring about or perform the functions or accomplishment as herein abovepointed out and explained.

From the above it is evident, that my present invention teaches anentirely new form of structure in the art of making assembled shearingsections for use in connection with electrically operated shavingimplements; a structure which is unique in its ability to reciprocatedlyadjust itself to the position of the face being shaved and to co-operatetherewith for engaging every curvature thereof for clean shaving; andwherein the spring member will actually cooperate with the operableaction of the inner movable cutter member; and although I have showncertain preferred forms or illustrations in order to explain anddescribe the novelty of my invention, yet, by showing such structure, Ido not, by any means, limit myself to these structures, nor to the termsused in describing same, as they are for illustrative purposes only.Various suggestions and changes of structure may be resorted to. Andalthough I mentioned of what material certain parts may be made, howthey may be formed, shaped or styled and how they may be assembled, yet,I desire it to be understood that this structure, or part thereof, maybe made of any suitable material, and shaped, formed. styled or arrangedin any desirable manner, and assembled in any suitable and convenientway so that the parts may be easily taken apart, removed, cleaned,replaced and reassembled, and that various changes in shape and indetail may be resorted to without departing from the spirit of thisinvention.
